How to Sell Crypto Without Getting Banned or Frozen
Account freezes can disrupt trading and cause stress. On platforms like OKX, most freezes result from suspicious behavior or policy violations. Here’s how to avoid them:
1. Complete KYC Verification
Verified accounts enjoy higher limits and fewer restrictions. Submit accurate ID documents early to prevent delays during large trades.

- Avoid logging in from different countries or IPs daily.
- Refrain from using VPS or proxy services unless necessary.
4. Follow Platform Rules
Read OKX’s user agreement carefully:
- Respect daily withdrawal limits.
- Comply with anti-scam policies.
- Report lost devices or compromised accounts immediately.

Never share login details with bots, signal groups, or “customer service” claiming to be from OKX.

- Enable 2FA using Google Authenticator (not SMS).
- Set up anti-phishing codes.
- Regularly update passwords.
7. Communicate Proactively
If flagged, contact OKX support promptly with evidence—such as transaction history or ID verification—to resolve issues faster.
